• Group 12 elements are classified as TM
• AM color lightened
• Categories removed (name or class): Unknown, Post-Transisiton metal, Reactive nonmetal.

New category (name or class): Other metal, Other Nonmetal, Halogen

• Reordering Category scheme (Nov 2020)

• 10 colors, no Unk, 2 repetitions

Issues

• No categories except ONONM, HAL, & NG meet AAA
• AM and AN do not meet AA
• PTM/MOID are too similar
• SoM should have other distinguishers in addition to, or instead of, color.
